Question on surface wrap(net) on a JD 467 baler?

Tx Jim

Well-known Member
Because of my disability I have to hire someone to operate my 467 rd baler while I watch. My operator kicks out a bale every once in a while that isn't wrapped. Operator states no buzzer or error codes are emitted from monitor. I've read all the netwrap trouble shooting outlined in the operators manual and can find nothing that states what to do when "no netwrap-no error code" happens. I think it's either "operator error" or an internal monitor problem. Anyone have any ideas.Thanks for any help,Jim
 
TX Jim: The bar/switch that tells you your out of mesh should tell you that the baler did not get mesh on it. This is only true if the mesh actually did not run. This switch is the little micro switch on the right side of the mesh wrap rolls. If you look a small "C" shaped channel runs across the baler. It pivots on two pins that are on one side of the channel. When the mesh wrap is cut it rubs across this channel. It swings because of this pressure. This motion trips the micro switch. If it does not swing the baler monitor should show no mesh alarm. I have had issues with hay/chaff getting behind this channel/bar and not working correctly. You just need to blow out the back side of it. Maybe lube the pivots.

The other thing that can be happening is that the mesh is getting wrapped around the top roll on the gate. I have trouble with this sometimes after the baler has set for a period of time. What happens is that the mesh wrap goes around the bale until it gets to the top where the belts change at the top two rollers. The mesh has to go across the gap from one roller to the next. Instead of going around the bale like it should it wraps the rear roller. If the wrap has a real ragged cut edge it will make this worse. Then the wrap will kind of pull off with the next bale but usually there is wrap around the ends/bearings. Clean the brush and check to see that the knife is sharp either can cause a too ragged cut edge.

If I get a non wrapped bale I stop and check right then. If it is wrapped on that top roll you can wipe out the bearings real fast. The wrap gets around them so tight I have had to take out the roll to get it off.

I also have two mirrors that look back at the baler. I can usually see with one of them if the bale has wrap on it. You can usually see the mesh between the belts or if you are looking in the pickup you can see that the hay is not dropping when it passes the throat opening.

Check the switch and check the rolls. If they are OK you more than likely have an operator issue.

The switch is number 20 in the picture.

Thanks for the reply. I have already checked and ruled out what you outlined. The thing that baffles me is there will be some netwrap lying under the exploded bale. That's why I was thinking operator error or monitor malfunction. My operator states "not me but machine problem. Yea right as this isn't my first rodeo.
Thanks again,Jim
 
My JD 467 does the same thing, I'm thinking I'm doing something wrong. I noticed when monitor says it's wrapping, it don't last long enough to make the right amount of wraps, usually one wrap and my monitor is set for 2 1/2 wraps . So, I just hit the wrap button and it puts the right amount. Takes a good bit longing baling, but they're all wrapped.

I blew off the brush but I fail to see the correlation between the brush and netwrap not getting wrapped around the bale. It appears to me than brush is intended to keep steel feed roller in netwrap attachment clean.
 
Another thought here.....you said there is a pile of
net under the broken bale....are you watching every
bale be kicked from the baler? Had a customer
complaining of net wrap not going on bales... headed
out to see what was going on...gate was being closed
to quickly and was catching the bale, breaking the
net. Like I said just a thought....diagnosis by
internet has its drawbacks.

If some netwrap is on bale or under exploded bale but not wrapped on any rollers won't that rule out the switch you referred to???

NO!! If that switch is not tripped the monitor thinks it is still warping the prior bale. There is series of things that have to happen in the correct order for the monitor to reset for the next bale. One of the last things is for this micro switch to be tripped. This tells the monitor that the prior bale is done and fully wrapped.

You saying you have a little wrap under the bale is telling me the bales is not completing the prior bale correctly and still thinks it is finishing it when the new bale starts to wrap.

It is a quark in the monitor that will allow this to happen. The half that is monitoring size is happy because it said to wrap the bale. The half that handles the actual wrap possess is not happy because it thinks it is not done with the prior bale.

So if that switch is not tripping every time it will make the monitor act real odd. As for the brush question. I don't think I said anything about a brush maybe being an issue. There is the brush that keeps the roll clean.

Another thing to think about. If the operator is jumping the gun and dumping the bale before the mesh wrap cycle is complete it will cause the monitor not to reset. I am meaning just a few seconds will do this. The bale is all done but tripping the micro switch. So the monitor may finish the prior wrap cycle rather than reset and start a new one. I have done this when really pushing bales of corn stalks through. You kind of get into a rhythm and hit the SCV without really thinking about it. You kind of jump the gun on the monitor finishing the wrap cycle. Then the next bale is not wrapped fully. It may only have a few feet of mesh under it. The monitor just finished the little bit it thinks it needed on the prior bale.
 
I fully understand the part of getting in a rhythm and then inadvertently open the gate too quick. Another detrimental thing is a "cell phone". I noticed yesterday on an unwrapped bale that the netwrap was only 20 ft long not approximately 34 ft like it should be.

Doesn't the monitor actually control the netwrap by way of the bale size indicator switch and all the cutoff switch on the RH rear of netwrap signifies if knife cut netwrap? As I sit and think about it the switch has to notify monitor if no net is fed through the rollers in netwrap attach also. I was having this same problem last year and I checked/reset the switch adjustment as outlined in the operators manual.

Yes the switch is just to tell if the mesh was cut or any mesh on the bale but if it is not tripped the monitor will not reset.. The monitor is putting mesh on the next bale but just not the amount you want. So the alarm is not sounding because it actually cuts the mesh and there is mesh there. I went through this on one a few years ago. Drove us nuts as it was totally random when it would miss a bale. In shredded corn stalks missing a bale is a real mess. On that baler I blew the micro switch out and it worked then. There are external springs in that micro switch, they are under the arm with the roller. They get dirt/dust in them and then the switch does not work correctly. That switch is an OLD JD part. They where used on the old style JD 200 series Flex heads for the header control.

Every step has to complete or the monitor will not reset all of the time. IT is rare for a monitor to fail in the way you are having problems. They usually just totally quit.

Thanks for the reply. I'm going to bale today so I'll blow out the switch. I've participated in baling shredded corn stalks. Oh what fun!!!
Thanks,Jim
 
On our 567 if we don't get 2 complete wraps on the
bale and the kickbar hits the spot with 1 wrap it
will sometimes explode the bale and then the bale
will land on the piled up mesh wrap not all of it
will be under the bale but most of it is.
 
Hey Jim-
I baled hay today with my 467 and the first 4 bales, 3 did not wrap, just some wrap but not over lapped. Brought the rig back to the shop, open it up, locked it out and started. What I found was the belt roller just under the wrap gismo had several wraps around it. Had to get inside to get it off. Cut it off and it works like it suppose to. I thought I had gone through this baler from top to bottom before I started, must not have seen it all. Hope this will help.
 

When I have netwrapping problems I always check rollers for escaped netwrap. I removed a little netwrap yesterday from the same roller you mentioned. Back when I was running Coveredge netwrap I was having net get on the little augers on each side. I've started using "edge to edge" to get more bales per roll and my cost per bale for net is very close to $1 per bale applying 2 wraps per bale. I blew off the brush and micro-switch and had "No net application failures" yesterday thanks to JD Seller.

My next question is why/how netwrap gets on the roller you mentioned when the netwrap is intended to stay outside the belts IE travel down outside of tailgate area belts between gate support & belts to get to hay on the bale??? I'm thinking the knife isn't cutting the net clean enough leaving strings that get caught by the belts.
